Review on 📺 J-Tech Digital JTD0104/4K 4 Port HDMI Splitter - Enhancing Ultra HD 4K 3840x2160 Resolution with 3D Support by Mike Lawler

The 1x4 4k splitter seemed to do what I needed but using it was more trouble than it was worth. I was trying to send an HDMI signal from a cable box to 3 TVs in my house. This block said it was auto-detect and auto-switch. There was video signal to all 3 TVs but there was snow on one screen. Sound was a big issue. Not all TVs always get sound, no matter how much or how little they are turned on. Restarting the splitter seemed to fix the problem, but it reoccurs as soon as you turn on the new TV or turn it off and on again. got really annoying so i gave up and went the other way. I am now using a J-Tech 1x2 1080 splitter to power just 2 TVs and it seems to be working fine.
